FIELD: volume- shaped laminated products. SUBSTANCE: the reticular sheathing has a great number of intersecting integral spiral and annular ribs. These ribs are made up of layers of systems of intersecting spiral and annular bands repeating in the thickness of the sheathing wall, as well as of band inclined transitions between the annular bands evenly shifted relative to one another in the peripheral and spiral directions. The ribs are coated with layers of external casing with respectively oriented in them unidirectional threads fastened by polymeric binder. The band inclined transitions between the annular bands of the annular ribs are located and fastened between the layers of the spiral ribs in the same directions and made with two turning angles respectively positioned in the points of intersection with the adjacent annular ribs. EFFECT: uniform distribution of reinforcing material of band inclined transitions between the annular bands of annular ribs. 5 cl, 7 dwg
